Development is an amazing thing to see in action, even for a pediatrician. For longer than I can remember I have been encouraging Joseph to keep trying the climbing walls that are pretty standard at parks and on most swing sets these days. In general he gives up pretty easily or I have to literally hurl him up the wall myself.
And then at our preschool picnic last week he just kicked off his shoes and zipped right up in no time, with no help at all. Then down the slide and up the wall again. And again and again. When did that happen?! How?!
The tongue sticking out always helps with concentration, but it's no wonder he can finally climb so well - look at the size of those feet! They measure in at 13!!!
